With integrated tunable Fabry-Pérot (FP) filter, LFP-3144C-337 features closed loop control, as driven by integrated ASIC and EEPROM, that improves center wavelength stability under influence of changing gravity; CWL is ±2 nm. Continuous capacitance measurements allow compensation for influence of gravity, low frequency vibrations, and temperature shifts. Detector covers tuning range of 3.1–4.4 µm, and EEPROM contains all calibration data for detector operation.
